€PanAmSat. ORIGINAL DR6 "RD Dessiber 1. 3004 Satalite and RECEIVED Rediocommubications Division Ms. Mariene Dortch, Secretary ‘10m@tonalBureau DEC — 1 2004 Federal Communications Commission en The Portals Building mmrxg:m:\::m l 445 12th Street, SW i Tw—As2s Washington, D.C. 20554 Re: 13 Communications, Interstate Electronics Corporation (IEC) Application for Earth Station Authority File No: SES—L1C—20020611—00939 Call Sign: E020160 Dear Ms. Dortch PanAmSat Corporation (*PanAmSat") received from L3 Communications, Interstate Electronics Corporation (IEC) ("TEC"), a letter, dated November 1, 2004, together with information pertaining to the above referenced application. TEC states that we should reply directly to the FCC on this matter and that the lack of a reply "within thirty calendar days from the date of this notice" would be construed "as an assent to the grant of IEC‘s earth station application". In similar situations, an affidavit is generally the result of an understanding between the operators of the satellitesinvolved (in this case PanAmSat and Intelsat). However, so far we have not been contacted by Intelsat with respect to this matter. In particular, PanAmSat is concerned with the following specific points: (i) TEC states "that the ESVs will operate with a 20.2° pointing accuracy"and then goes on to say that "the operator will terminate ESV transmission when the antenna goes beyond 20.5°%. These statements lead to the understanding that the pointing accuracy is actually 20.5° and the matter needs clarification. (ii) According to the ESV link parameters provided by IEC, it is concluded that the input power density to the antenna may exceed by more than 5 dB the 1sox smm n« surme sn« wasinmron, Do zoo «usn «on1 m sn« oc e ire

value set in 47CIFR. §25.212(c). This fact combined with the pointing accuracy problems discussed in () above raise concerns about the potential for interference to PanAmSat uplinks. (ii) TBC provides a brief description of the antenna system stabilization but PanAmSat would like to know more details about the capabilities of such stabilization system. In view of the points discussed above, PanAmSat is concemed about the potentialfor interference from TEC earth stations to PanAmSat satellites at 95° W and 99° W and, in the absence of further clarifications and possible adjustments in the application, is not i a position to agree with the grant of such application.
